Hello.
So, yesterday I downloaded Ubuntu 18.04 ISO file and then copied the files to the USB Drive by Rufus. Then, I restarted my PC and on the boot menu I had 2 options, UEFI Kingston or just Kingston USB, without that UEFI prefix. I choose the first option, UEFI. It booted successfully, but there was a problem at the end of the installation of Ubuntu: "grub-efi-amd64-signed installation failed". Then I searched forums on the internet and found something, the people said that I need to choose the 2nd option, without UEFI prefix and to turn off ACPI. I choose that, and then problems started. I won't say anything more, I'll put a video there, I can't explain this. I can just say that I tried to turn ACPI off, the errors disappeared but when I tried to install it, the purple screen freezed. Thanks in advance.
